It's an interesting question though, I mean a lot of us here have been capable of "holding our noses" wrt various aspects of games, and it's true that BW games have been pozzed (as opposed to just, "why can't we all just get along?" type liberal) for quite some time, probably since about JE as someone said above.
So what's the "tipping point?" What's making me absolutely unwilling to follow BW into Veilguard, while I was kind of okay with DA:I (even though it was right at the edge of my tolerance)?
One important thing is the vague memory of the good times one had with DA:O. That was quite strong through DA2 and even DA:I had a lingering perfume of it. DA:I still felt like the same virtual world to some extent, and that was enough to induce me to keep up the nose-holding.
Then, even up to DA:I, the poz was still being offered as an option (the saving grace of BG3's poz btw). But as with a lot of modern product, it looks like this game has tipped over into it being the only way to play the game.
I think that's the tipping point generally; one can hold one's nose so long as the putrid stuff is still an option that one can more or less adroitly avoid, but when it becomes the whole of the product, that's it for me.
So say, with BW and a lot of game developers, for a long time, they had liberal or pozzed elements, but they were introduced in the context of "why can't we all just get along?" liberality. Over time the "you should appreciate this or you're a bigot" element got strong and stronger, till now, there's literally no escape. One feels like the guy in a Clockwork Orange, with one's eyeballs peeled back, forced to watch the horror.
But of course one isn't forced. Yet. One can still refuse to give one's life blood for the crap.
